Question

In the electrochemical cell composed of two half cells, the ions flow from one half-cell to another through?

1) electrolysis
2) aid
3) a salt bridge
4) a wire

Answer 1

In an electrochemical cell, ions flow from one half-cell to another through a salt bridge to maintain electrical neutrality.

Step-by-step explanation:

In an electrochemical cell composed of two separate half cells, the ions flow from one half-cell to another through a salt bridge. The purpose of the salt bridge is to maintain electrical neutrality within the cell by balancing the charge as the reaction proceeds.

Electrons are transferred from the anode, the negative electrode where oxidation occurs, to the cathode, the positive electrode where reduction occurs, via an external wire connecting the two.
